Summilux-M 35mm f/1.4 ASPH

This lens was introduced in 1994
and represented a milestone in lens development. It was the first
Leica aspherical lens produced by moulding raw glass blanks (a
new, quicker and more cost-effective technology) and represented
the start of the use of the new aspherical technology for a complete
range of spectacular lens innovations.

The Summilux-M 35mm f/1.4 ASPH
is an ultra-high-speed wide-angle lens that consists of nine
elements in five groups. The abbreviation "ASPH" added
to the name, applies to the aspherical lens surface that provides
this optical system with an unsurpassable image performance.
A performance unlike that of any other compact 35mm lens: high
contrast, excellent reproduction of detail in the image field,
good even image field, and virtually free of coma. For the purpose
of practical photography, the slight barrel shaped distortion
is hardly noticeable.

Vignetting occurs in all optical
systems. In this lens, it is negligible at full aperture and
no longer visible at f/4.0.

These performance characteristics
remain even in close ranges down to 0.7m. The Summilux-M 35mm
f/1.4 ASPH can be used universally as a versatile wide-angle
lens.
